I opened a few foreign deposit accounts during 2023 and have already received some interest from these. All of my other income is PAYE and the foreign deposit interest I expect to earn annually is well below €5,000. I plan to submit a Form 12 tax return.
From reviewing this website and Revenue's own site, I see that preliminary tax for the year 2023 is due to be paid by 31/10/2023 and seems to cover income tax, PRSI, and USC. The focus of advice online is understandably on Form 11 taxpayers and how Revenue go about collecting labour income taxes promptly. Otherwise, the guidance on preliminary tax seems quite generic and unhelpful for my case.
Do I need to pay preliminary tax on 2023 foreign interest income (or expected interest for the year) by 31/10/2023? Or do I have until 31/10/2024 to fill out a Form 12 and pay outstanding DIRT for the year 2023?
If there is no clear guidance from Revenue, what do AAM posters do when declaring foreign deposit income?
